摘要：Recent research efforts to design better Internet transport protocols combined with scalable Active Queue Management(AQM) have led to significant advances in congestion control. One of the hottest topics in this area is the design of discretecongestion control algorithms that are asymptotically stable under heterogeneous feedback delay and whose control equations donot explicitly depend on the RTTs of end-flows. In this paper, we first prove that single-link congestion control methods with astable radial Jacobian remain stable under arbitrary feedback delay (including heterogeneous directional delays) and that thestability condition of such methods does not involve any of the delays. We then extend this result to generic networks with fixedconsistent bottleneck assignments and max-min network feedback. To demonstrate the practicality of the obtained result, wechange the original controller in Kelly’s work [15] to become robust under random feedback delay and fixed constants of thecontrol equation. We call the resulting framework Max-min Kelly Control (MKC) and show that it offers smooth sending rate,exponential convergence to efficiency, and fast convergence to fairness, all of which make it appealing for future high-speednetworks
